PMT may confound the interpretation of immediate postoperative outcome. Follow-up is recommended to definitely evaluate surgical results.

BACKGROUND: There are no large-scale epidemiological studies on primary hyperparathyroidism (PHPT) in Russia. The high prevalence of the disease, the high risk of disability and death in this cohort of patients requires the study of the epidemiological and clinical structure of PHPT to determine the extent of medical care. AIM: Evaluate the frequency of PHPT detection and characterize its clinical forms in Russia using an online registry. METHODS: The object of the study is the database of the State Register of Patients with PHPT 1914 patients from 71 regions of the Russian Federation. New cases of the disease, as well as dynamic indicators are recorded when patients visit outpatient clinics or medical institutions. The analysis of data made at the end of December 2017 was carried out. The following parameters were evaluated: demographic and clinical indicators; indicators of phosphorus-calcium metabolism, the main forms of PHPT and its course, the primary characteristic of PHPT in hereditary syndromes and parathyroid carcinoma. Results are presented as mean and standard deviations, or medians and quartiles; descriptive statistics of qualitative attributes absolute and relative frequencies. RESULTS: the total number of patients with PHPT in the registry on 31 of December 2017 was 1914 cases (0.001% of the population of the Russian Federation). Identification of PHPT was 1.3 cases per 100 thousand of the population in Russia, 7.6 cases in Moscow, 6.1 cases per 100 thousand in the Moscow region. The average age of patients at the time of diagnosis was 55.6 10 years. The active phase of the disease was registered in 84.6% of patients (1620/1914), most of whom had a symptomatic PHPT 67.1% (1087/1620), and 32.9% a asymptomatic disease (533/1620). Symptomatic disease with visceral complications was detected in 15.8% cases (172/1087), with bone complications in 48.4% (526/1087). The mixed form of the disease was detected in 35.8% of patients with manifest form (389/1087). Normocalcemic variant PHPT (nPHPT) was registered in 14.5% cases (234/1620). Sporadic PHPT occurs in 83% of cases (1592/1914). 326 patients (17%) had a suspicion for hereditary form of the disease: average age was 31.2 12.3 years. A genetic analysis was conducted in 61 patients (3.2%): showed the mutation in the MEN1 gene in 2.9% of cases (55/1914) and the mutation in the CDC73 gene in 0.3% of cases (6/1914) (HPT-JT syndrome). Parathyroid carcinoma was confirmed in 1.8% of all patients (35/1914). Surgical treatment was performed in 64.5% of patients (1234/1914). Remission was achieved in 94% of cases (1160/1234), in 6% of cases relapse after surgical treatment or persistence of PHPT was recorded. CONCLUSION: detection of PHPT in the Russian Federation raised in comparison to 2016, which is associated with an active start of registration of patients in the regions. At this stage, it is necessary to modify the principles of registration and control, to make a platform for gathering information and calculating the necessary volumes of medical care for PHPT patients.

The study included 18 patients (10 females and 8 males) with a not less than 2 year-history of type 1 diabetes (T1D), who had received insulin therapy since its diagnosis was established. The patients ’ mean age was 32.9± 13.0 years; the mean duration of TID was 15.1+11.5 years; the mean daily dose of insulin was 40.1+16.0 units; the mean level of glycosylated hemoglobin (HbAJ was 9.4±2.1% (the normal value 4.4-4.9%). The glycemic curve symmetrization method proposed for statistical analysis of glycemic self-control is also quite suitable for the statistical monitoring of a continuous daily glycemic curve. The high and low glycemic indices calculated from the symmetrized glycemic data correlate well with the level of HbAk and with the duration of hypoglycemia and hyperglycemia and hence they may be used as additional criteria for a risk of diabetes complications. The criteria, calculated from the symmetrized data of glycemia for the risk of hyper- and hypoglycemia, adequately reflect the behavior of a continuous glycemic curve and may be used as integral indices of the efficiency of glucose-reducing therapy in clinical practice.

Due to continuous aging of population and increase in the number of elderly people, osteoporosis became socially significant disease leading to disability, increasing mortality and thereby putting an additional burden on the public healthcare system.Screening to identify groups with a high probability of fracture is recommended using the FRAX® Tool for all postmenopausal women and men over 50 years old (А1). In the presense of major pathological fractures (hip, spine, multiple fractures) it is recommended to diagnose osteoporosis and prescribe treatment regardless of the results of spine and hip double X-ray absorptiometry (DXA) or FRAX® (B2).It is recommended to evaluate C-terminal telopeptide when prescribing antiresorptive therapy and procollagen type 1 N-terminal propeptide (P1NP) when prescribing anabolic therapy to patients receiving osteoporosis treatment at baseline and 3 months after the start of therapy in order to assess the effectiveness of treatment early and adherence to the therapy (А2). It is recommended to diagnose osteoporosis and prescribe treatment to patients with high individual 10-year probability of major pathological fractures (FRAX®) regardless of the results of spine and hip DXA (В3).It is recommended to diagnose osteoporosis and prescribe treatment with a decrease in BMD, measured by DXA, by 2.5 or more T-score standard deviations in femoral neck, and/or in total hip, and/or in lumbar vertebrae, in postmenopausal women and men over 50 years old (А2).It is recommended to prescribe bisphosphonates, denosumab or teriparatide to prevent pathological fractures and increase BMD in patients with postmenopausal osteoporosis, osteoporosis in men, glucocorticoid-induced osteoporosis (А2). When the clinical effect of therapy in osteoporotic patients without pathological fractures is achieved (BMD T-score > -2.0 SD in femoral neck and absence of new fractures), it is recommended to interrupt bisphosphonates therapy for 1-2 years with subsequent follow-up (B2). In patients with vertebral fractures, hip fractures or multiple fractures, it is recommended to continue ceaseless long-term treatment of osteoporosis (В3).All drugs for the treatment of osteoporosis are recommended to be prescribed in combination with calcium and cholecalciferol (А2). In order to reduce the risk of recurrent fractures by prescribing osteoporosis therapy timely and maintaining long-term follow-up of patients over 50 years old with pathological fractures, it is recommended to create Fracture Liaison Services (В2).
